Ricardo Cuba's CLI Market positions itself as commerce infrastructure for AI agents, solving the problem that every retailer has a different API, authentication mechanism, schema, and checkout flow. The tool is installed via `pip install cli-market-world` and initialized with `market init`, after which agents can run commands like `market search "rice" --country PE --json` to query 38 active retailers in under one second. A single CLI Market token handles all retailer authentication, and the tool normalizes queries so that "arroz", "rice", and "arroz blanco" all resolve to the same product. Results are returned as structured JSON including product name, price, price per kg/L, store name, country, and a `refreshed_at` timestamp, with data refreshed every 4 hours.
The post describes intended use cases including price monitoring across LATAM, shopping assistants, competitive intelligence, and supply chain optimization.
The tool exposes 22 curated MCP tools (and 46 legacy tools) covering search, compare, basket, and checkout paths, and is described as connectable to Cursor or any MCP client in 30 seconds. A Pro tier adds historical price data. The post describes intended use cases including price monitoring across LATAM, shopping assistants, competitive intelligence, and supply chain optimization. Cart and checkout functionality — enabling agents to complete purchases rather than just search — is listed as in development.
